Answer:
If a country has a low GDP, it produces a low number of goods each year, resulting in an economically poor nation
Explanation:
Answer:
The concave slope is represented by the closely spaced contour in the upper locations and gradually become widely spaced in the lower areas. - Convex slope is a geographical feature with inconstant slopes. The upper part is less steep than the lower part.
Explanation:
The correct answer is - deforestation.
Deforestation is a huge issue when it comes to soil erosion. When there's thicker vegetation the soil is in place and the erosion is minimal. This is due to the root systems of the trees, bushes, grashes, that are making a natural net inside the soil that holds it in place and doesn't allow the soil to be moved away and thus erosion to take place. But when we have a deforested landscape than the situation is the total opposite. The soil is left on its own and it doesn't have any protection from the root systems to keep in place, so with every rain it is eroding slowly and occasionally quickly when there's heavy rainfall. Most of the erosion takes place on the steeper parts.
Answer:
When a wave is too steep to support itself, the wavefront collapses creating a <u> </u><u>break </u>that advances up the shoreline
Explanation:
When waves are tall, with a great slope that makes them unstable, they break. Braking waves might occur inshore or offshore.
- Offshore: Breaking waves in the deep sea occurs when the wind speed increases so fast that they exceed the speed of the waves. These last ones acquire additional energy from the winds increasing their slopes to the point of being so unstable that the water from the crest falls forward and breaks the wave. The most influencing factor in these breaking waves is the speed of the winds.
- Inshore: When waves are near the shore, the scarce water deepness increases the friction of the wave with the marine bottom, and consequently, the wave´s speed decreases progressively. The wave loses energy in the friction, the wave energy is concentrated in a lower length, and the wave grows in size. As it increases, it acquires a sharper slope. As deepness decreases, the wave base loses speed, but the crest does not. As the wave crest travels faster, the frontal face of the wave becomes concave. This change in shape continues until the wave can not support itself and it breaks. The break is not produced by the friction with the bottom, but by exceeding the slope limit values.
